[DeTomaso] gumball pantera purging air from cooling system

[LEVITT1946 at aol.com]

Dear Friends,
 
 
My Cooling system is set up as follows;
 
fluidyne radiator leaning forward
 
sucker fans on ALL the time 
 
Antifreeze  50/50 blend 
 
New High Flow Water pump
 
160 thermostat( correct for cleveland)
 
I Used this tool to suck all air out of system and put the  antifreeze back 
in:
 
UView 550000 Airlift Cooling  System Leak Checker and Airlock Purge Tool Kit
 

On the open road the car runs at a  steady 180. As soon as I get into stop 
and go traffic or go from waiting at red  lights I can see the temp gauge 
start climbing 220 plus . In the heat  of the summer months I feel like the 
car is ready to blow  hoses. 
I have read that guys here in the  group have cars that sit in the desert 
sun all day and the temp gauge barely  moves. Either their gauges are broken 
or I have a system that the antifreeze is  just not flowing and cooling 
.When I bought the car three years ago the guy  said," If you are caught in 
traffic ,just pull over". I refuse to believe that  Detomaso designed the car to 
overheat. I see Ferrari's,Lambo's and  Porsche run cool.So why can't the 
Pantera?  
I told my high temp issues to a  guy last week at one of the cruise in's 
and he said to me that back in the 70's  and 80's he developed a system that 
would lower the cooling temp by at least 20  degrees. He said that the 
cleveland engine in a pantera leans down at the  firewall and the heads will 
always get air trapped at the rear of the  head.(back of car) Causing there 
airlock situation and therefore  restricting flow. 
What he does is drill a hole  into each head and runs stainless lines to 
the pressure tank or  the the overflow tank,I forgot which one. 
Does this make sense to anyone ? Has  anyone every done this and had 
success? 
This guy did not seem like a typical  back yard mechanic .He designed this 
process while he was working for a speed  shop out here in New York called 
Motion.
Please let me know your thoughts  .
Regards,
Bob Levitt
